Attention
RS485_3 and RS485_5 can control the input and output direction automatically. There’s no need to control it from within the software.
The 120Ω match resistor for RS485 is NOT mounted by default.
The 120Ω match resistor for CAN is NOT mounted by default. Be sure to mount the match resistor when testing CAN.
RS485_3 and RS232_3 share UART3 and can’t work at the same time; RS485_5 and RS232_5 share UART5 and can’t work at the same time. Meaning the product provides 4 x RS232 + 0 x RS485, or 2 x RS232 + 2 x RS485, or 3 x RS232 + 1 x RS485.
GPIO Port¶
The CS-CM5-BOX industrial Pi PC has a 10 Pin 3.81mm GPIO Connector, as shown in the figure below. The table below gives details about the definition of every Pin.
Attention
In order to use the Isolated Output, you need to add an external Isolated Power to the VDD_ISO and GND_ISO. The power voltage should not exceed 24V.
The output current can achieve 500mA for every channel, but it also depends on the isolated power that is connected.
In order to use the Isolated Input, you need to add a signal to the ISO_InputX and GND_ISO. A 2.4KΩ resistor, as R6, has been added to limit the input current, as shown in the figure below. This resistor should work well for the 5-24V input signal. If your input signal is less than 5V, please change this input resistor. The reduced schematic is for reference purpose, if you need the precise resistor schematic, please contact us.

USB Connectors¶
There are 1 x USB 3.0 type-A Host, 1 x USB 2.0 type-A Host, 1 x USB type-C OTG onboard, as shown in the figure below.
USB HOST Connectors
Attention
1. These two USB host connectors can drive 500mA for each channel at most.
2. The USB3.0 comes directly from Raspberry Pi CM5.
3. When you connect this product to the HOST PC through the Type-C port, the USB2.0 type-A port will be disabled. As a result, the USB2.0 type-A port will not work until type-C is disconnected.
The product has one USB Type-C OTG connector that works as a slave by default. You can use it to establish a connection with the host PC and for downloading the system to the eMMC of CM5 module.
USB Type-C OTG Connector
Warning
Be careful not to touch surrounding electronic components accidentally while plugging in USB devices into the embedded Industrial PC version.
LAN¶
The 2 x Giga LAN provides Ethernet connectivity over standardized Ethernet cables as shown in the figure below. The integrated Ethernet interface supports up to 1 Gbps data throughput. These Giga LAN signals come from the CM5 module directly.
RJ45 LAN Connector
Note
Use CAT5 or better cables to achieve full data throughput over maximum distance defined by the 1000BASE-T standard (100m).
WiFi & BT Module¶
The default CS-CM5-BOX without the CM5 does not include a Wi-Fi/BT module.
If you include a CM5 that has the Wi-Fi/BT module, the product will have Wi-Fi/BT feature.
The product also has an SMA connector for an external WiFi/BT antenna:
